Answer 1

You want to convert the ints to strings, and join them with commas. You can do this with streams.

int[] intArray = {234, 808, 342};
String s = Arrays.stream(intArray)
                 .mapToObj(String::valueOf) // convert each int to a string
                 .collect(Collectors.joining(", ")); // join them with ", "

Result:

"234, 808, 342"
